There are sooooooo many reasons not to house multiple snakes together that I completely threw out the thought of ever doing it when I joined this forum. Cannibalism, stress, one snake dominating the other(this looks like they are cuddling but in all reality they are in a sense fighting), sickness(if one snake gets sick and you need to get a fecal sample how could you tell the poo apart?), competition for food. Just to name a few. The best way to do things is to get every snake their own enclosure. This makes things soooooo much easier on us keepers.
